Sorry, I just have one more quick question.
Bug 1:
Nonetheless, for read(), I was just wondering, if you read from a list input
then it should be like that.
However, if it is just a raw string and it acted like that, then how do you
tell if a string is an invalid integer string?
Do you have to build a check for that then? Shouldn't read() be able to detect
that because if you build a check on top of that, you would have to go through
all the character one and then read would then goes through all the characters
again.
Bug 2:
As you said that it is not a bug. I just suggested that for -2147483648, it is
still assignable with range check on, you just have to assign -2147483647 - 1
